Description

Technical Field

[0001] This application relates to the field of electrical control device technology, and more specifically, to a relay. Background Technology

[0002] A relay is an electronic control device that has a control system (also known as an input circuit) and a controlled system (also known as an output circuit), and is commonly used in automatic control circuits. Essentially, a relay is an "automatic switch" that uses a smaller current to control a larger current. Therefore, it plays a role in automatic adjustment, safety protection, and circuit switching in circuits.

[0003] A magnetic latching relay, as one type of relay, includes a contact portion, an armature assembly, a coil assembly, and an auxiliary monitoring portion. The armature assembly is configured to be movable, driving the contact portion to switch between a closed and open state. The coil assembly is electromagnetically coupled to the armature assembly, driving the armature assembly's movement. The auxiliary monitoring portion has an auxiliary moving spring and an auxiliary lead-out. The auxiliary moving spring is connected to the armature assembly and is used to contact or separate from the auxiliary lead-out. The contact state of the contact portion is determined by monitoring the contact state between the auxiliary moving spring and the auxiliary lead-out. However, in related technologies, the connection structure between the auxiliary moving spring and the armature assembly is overly complex, thus affecting the assembly efficiency of the auxiliary moving spring and the armature assembly.

Detailed Implementation

[0040] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this application will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.

[0041] It is understood that the terms "comprising" and "having," and any variations thereof, in the embodiments of this application are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the steps or units listed, but may optionally include steps or units not listed, or may optionally include other steps or components inherent to these processes, methods, products, or devices.

[0042] like Figure 1 and Figure 2 As shown, this application embodiment provides a relay, which can be a magnetic latching relay, but is not limited thereto. The relay includes a housing 100, a contact portion 200, and a magnetic circuit drive portion 300, which are disposed within the housing 100. The contact portion 200 has a closed state and an open state, and the magnetic circuit drive portion 300 is configured to drive the contact portion 200 to switch from a closed state to an open state and from an open state to a closed state in response to an input signal.

[0043] In one implementation, such as Figure 2As shown, the housing 100 may include a top cover 110 and a base 120, which are connected together to form a hollow cavity for accommodating the contact portion 200 and the magnetic circuit drive portion 300. The shape of the top cover 110 after connecting with the base 120 can have various embodiments. For example, in the embodiment of this application, the shape of the top cover 110 after connecting with the base 120 is a hollow cuboid. Of course, in other embodiments, the shape of the top cover 110 after connecting with the base 120 can also be a hollow cylinder, or other suitable shapes.

[0044] As an example, the base 120 includes a receiving cavity 121 with an opening, and the base 120 is cuboid in shape. The contact portion 200 and the magnetic circuit driving portion 300 are installed in the receiving cavity 121 of the base 120 through the opening of the base 120. The top cover 110 is plate-shaped and is fastened to the opening of the base 120 to form a hollow cuboid.

[0045] Of course, in other embodiments, both the top cover 110 and the base 120 are cuboid in shape and have an opening on one side. The opening of the top cover 110 is opposite to the opening of the base 120, and the top cover 110 and the base 120 are fastened together to form a hollow cavity for accommodating the contact portion 200 and the magnetic circuit drive portion 300.

[0046] like Figure 2 As shown, the magnetic circuit drive section 300 includes an armature assembly 310 and a coil assembly 320. The armature assembly 310 is movably disposed within the base 120 and connected to the contact portion 200, used to drive the contact portion 200 to switch from a closed state to an open state and from an open state to a closed state. The coil assembly 320 is fixed within the base 120 and electromagnetically coupled to the armature assembly 310, and the coil assembly 320 is configured to drive the armature assembly 310 to move in response to an input signal.

[0047] like Figure 2 , Figure 3 and Figure 4 As shown, the relay also includes an auxiliary monitoring section 600, which includes an auxiliary moving spring 610 and two auxiliary leads 620. The auxiliary moving spring 610 is fixedly inserted into the armature assembly 310, and the auxiliary leads 620 are mounted on the housing 100, with portions of the auxiliary leads 620 extending out of the outer surface of the housing 100 for connection to an external circuit. The auxiliary moving spring 610 is used to contact or separate from the auxiliary leads 620.

[0048] The auxiliary moving spring 610 has two positions relative to the auxiliary leads 620: a contact position and a separation position. When the auxiliary moving spring 610 is in the contact position, it is in contact with both auxiliary leads 620. When the auxiliary moving spring 610 is in the separation position, it is separated from both auxiliary leads 620.

[0049] When the contact portion 200 is in the closed state, the auxiliary moving spring 610 is located in one of the contact position and the separation position; when the contact portion 200 is in the open state, the auxiliary moving spring 610 is located in the other of the contact position and the separation position.

[0050] In detail, when the contact part 200 is in the open state, the auxiliary moving spring 610 is in contact with the two auxiliary leads 620, and the auxiliary monitoring part 600 is normally closed at this time; when the contact part 200 is in the open state, the auxiliary moving spring 610 is separated from the two auxiliary leads 620, and the auxiliary monitoring part 600 is normally open at this time.

[0051] Understandably, the auxiliary moving spring 610 is mounted on the armature assembly 310. When the coil assembly 320 drives the armature assembly 310 to move, the auxiliary moving spring 610 also moves accordingly, thereby achieving contact or separation between the auxiliary moving spring 610 and the auxiliary lead-out member 620. Therefore, by monitoring the contact and separation state between the auxiliary moving spring 610 and the auxiliary lead-out member 620, the contact and separation state of the contact portion 200 can be determined.

[0052] like Figure 3 and Figure 5 As shown, the armature assembly 310 has a groove 3152, in which the auxiliary moving spring 610 is inserted. The relay also includes a glue (not shown in the figure), which is disposed in the groove 3152 and is used to fix the auxiliary moving spring 610 and the armature assembly 310 together. The glue can bond the auxiliary moving spring 610 and the armature assembly 310 together.

[0053] Understandably, the colloid can be, but is not limited to, the solidified substance of an adhesive.

[0054] In the relay of this application embodiment, the auxiliary moving spring 610 and the armature assembly 310 are connected by a plug-in method. On the one hand, the auxiliary moving spring 610 and the armature assembly 310 can be molded separately, reducing the processing difficulty of each component; on the other hand, the plug-in connection method can improve the assembly efficiency of the auxiliary moving spring 610 and the armature assembly 310; furthermore, the colloid fixes the auxiliary moving spring 610 and the armature assembly 310 together, which can improve the connection strength between the auxiliary moving spring 610 and the armature assembly 310 and prevent the auxiliary moving spring 610 from shaking relative to the armature assembly 310.

[0055] In one embodiment, the auxiliary lead-out member 620 may be a needle-like structure. Of course, in other embodiments, the auxiliary lead-out member 620 may also be a sheet-like structure, and this application does not particularly limit this.

[0056] In one embodiment, the auxiliary lead 620 may be made of copper to increase the conductivity of the auxiliary lead 620, but is not limited thereto.

[0057] like Figure 3 As shown, the armature assembly 310 includes a package 315, a permanent magnet (not shown), and two armatures 311. The package 315 connects the permanent magnet and the two armatures 311 into a single unit. The package 315 has a groove 3152.

[0058] In one embodiment, an auxiliary moving spring 610 is disposed on the side of the package 315 facing or away from the coil assembly 320, so that the auxiliary moving spring 610 can extend along the length direction of the package 315 and / or the coil assembly 320, thereby reducing space occupation, improving the flexibility of the auxiliary moving spring 610 and reducing reaction force.

[0059] In one embodiment, the reciprocating motion trajectory of the armature assembly 310 is parallel to a plane, and the insertion direction of the auxiliary moving spring 610 and the armature assembly 310 is perpendicular to the plane.

[0060] In this embodiment of the application, since the insertion direction of the auxiliary moving spring 610 is perpendicular to the plane, the auxiliary moving spring 610 is not easy to fall out of the groove 3152 during the reciprocating motion of the armature assembly 310, thus ensuring the reliability of the auxiliary monitoring.

[0061] It should be noted that the armature assembly 310 can move linearly or oscillate back and forth.

[0062] like Figure 2 , Figure 3 and Figure 5 As shown, the base 120 has a base plate 123, the package 315 has a mounting portion 3151, and the groove 3152 is formed by recessing into the mounting portion 3151 from the side surface of the mounting portion 3151 facing away from the base plate 123 and in a direction perpendicular to the base plate 123.

[0063] In one embodiment, the auxiliary moving spring 610 is inserted into the groove 3152 in a direction perpendicular to the base plate 123.

[0064] like Figure 8As shown, the auxiliary moving spring 610 has a sheet-like structure and moves along the armature assembly 310. The auxiliary moving spring 610 includes a plug-in portion 611 and two contact portions 612. The two contact portions 612 are symmetrically connected to both ends of the plug-in portion 611 along the arrangement direction of the two auxiliary leads 620. The two contact portions 612 are used to contact or separate from the two auxiliary leads 620 respectively. At least a portion of the plug-in portion 611 is inserted into the groove 3152.

[0065] like Figure 5 and Figure 6 As shown, the groove 3152 has a first slot 3153 and a second slot 3154. The first slot 3153 and the second slot 3154 are arranged along the insertion direction of the insertion part 611, and the first slot 3153 and the second slot 3154 are connected.

[0066] like Figure 6 , Figure 7 and Figure 8 As shown, the plug-in portion 611 includes a first plug-in portion 6111 and a second plug-in portion 6112. At least a portion of the first plug-in portion 6111 is inserted into the first slot 3153, and the first plug-in portion 6111 and the first slot 3153 are mutually positioned and engaged along the arrangement direction of the two auxiliary leads 620 and the thickness direction of the plug-in portion 611. At least a portion of the second plug-in portion 6112 is inserted into the second slot 3154, and two contact portions 612 are symmetrically connected at both ends of the second plug-in portion 6112 along the arrangement direction of the two auxiliary leads 620.

[0067] In this embodiment, the armature assembly 310 can form a closed groove around the first insertion part 6111 to accommodate the adhesive and prevent the adhesive from flowing out from both sides. The first insertion part 6111 mainly serves to fix and position. Two contact parts 612 are connected to the second insertion part 6112 and extend from both sides of the groove. The second insertion part 6112 is used to assist in fixing and to connect the contact parts 612.

[0068] like Figure 5 and Figure 10As shown, the mounting portion 3151 includes a base 3151a, a first protrusion 3151b, and a second protrusion 3151c. A first slot 3153 is recessed on the side of the base 3151a facing away from the base plate 123, and the first protrusion 3151b and the second protrusion 3151c protrude from that side of the base 3151a. In one embodiment, the first protrusion 3151b and the second protrusion 3151c protrude from the side of the base 3151a facing away from the base plate 123. The first protrusion 3151b and the second protrusion 3151c are arranged at intervals along the thickness direction of the auxiliary moving spring and form a second slot 3154. The second insertion part 6112 is located between the first protrusion 3151b and the second protrusion 3151c. There is a first gap G1 between the second insertion part 6112 and the first protrusion 3151b, and a second gap G2 between the second insertion part 6112 and the second protrusion 3151c.

[0069] In this embodiment, after the second insertion part 6112 is inserted between the first protrusion 3151b and the second protrusion 3151c, it does not contact the first protrusion 3151b and the second protrusion 3151c. Instead, it has a first gap G1 and a second gap G2. The setting of the first gap G1 and the second gap G2 increases the distance between the first protrusion 3151b and the second protrusion 3151c. The larger distance provides the insertion part 611 with a tolerance space. During the process of the insertion part 611 being inserted into the groove 3152, even if there is a slight misalignment between the insertion part 611 and the opening of the first slot 3153, the insertion part 611 can still be smoothly inserted into the groove 3152. Furthermore, the insertion part 611 is less likely to generate scraping debris with the first protrusion 3151b and the second protrusion 3151c.

[0070] like Figure 5 and Figure 10 As shown, the second protrusion 3151c is further provided with a glue injection groove 3151d on the side opposite to the base 3151a, and the glue injection groove 3151d communicates with the second slot 3154. In this embodiment, the glue injection groove 3151d can temporarily hold glue, preventing overflow due to the glue not being able to flow quickly into the second slot 3154. In addition, after the glue in the glue injection groove 3151d cures, it can further improve the firmness of the connection between the auxiliary moving spring 610 and the mounting part 3151.

[0071] like Figure 7As shown, the first slot 3153 is provided with a partition 3155, which divides the first slot 3153 into two sub-slots 3153a. The two sub-slots 3153a are arranged along the arrangement direction of the two auxiliary lead-out members 620. The first plug-in part 6111 has two plug-in arms 6111a, which are connected to the side surface of the second plug-in part 6112 facing the sub-slots 3153a and are respectively plugged into the two sub-slots 3153a.

[0072] In this embodiment, two plug arms 6111a are respectively inserted into two sub-slots 3153a. The two sets of corresponding plug arms 6111a and sub-slots 3153a improve the stability after the auxiliary spring 610 is connected to the mounting part 3151. Compared with the solution where the first plug part 6111 has only one part, the first plug part 6111 in this embodiment has two plug arms 6111a, which increases the number of sides that cooperate with the groove 3152 in the arrangement direction of the two auxiliary leads 620. This allows the first plug part 6111 to fit against the groove 3152 to achieve a limiting fit in the arrangement direction of the two auxiliary leads 620, while also being able to gap fit with the groove 3152 to provide space for adhesive.

[0073] In one embodiment, the partition 3155 contacts the side surface of the second insertion part 6112 facing the sub-slot 3153a, and each insertion arm 6111a has a first adhesive-receiving gap 3156 between the end away from the second insertion part 6112 and the bottom surface of the corresponding sub-slot 3153a. The first adhesive-receiving gap 3156 communicates with the second slot 3154, and part of the adhesive is filled in the first adhesive-receiving gap 3156.

[0074] In this embodiment, during the insertion of the two plug arms 6111a into the two sub-slots 3153a, the second plug portion 6112 gradually approaches the separator 3155. When the second plug portion 6112 contacts the separator 3155, the two plug arms 6111a are fully inserted. On one hand, the contact between the separator 3155 and the second plug portion 6112 can improve the stability of the auxiliary moving spring 610 after it is connected to the package 315 to a certain extent. On the other hand, the separator 3155 can play a positioning and limiting role, so that a first adhesive-receiving gap 3156 with a sufficient width is formed between the plug arm 6111a and the bottom surface of the sub-slot 3153a, so that the adhesive can flow into the first adhesive-receiving gap 3156, thereby improving the connection strength between the plug arm 6111a and the mounting portion 3151.

[0075] Continue reading Figure 7The insert arm 6111a has a second adhesive-receiving slit 3157 between its surface facing the partition 3155 and the partition 3155. The second adhesive-receiving slit 3157 communicates with the second slot 3154 and the first adhesive-receiving slit 3156. Part of the adhesive fills the second adhesive-receiving slit 3157. During adhesive injection, the adhesive flows sequentially through the second slot 3154 and the second adhesive-receiving slit 3157 into the first adhesive-receiving slit 3156. After the first adhesive-receiving slit 3156 is filled, the adhesive then sequentially fills the second adhesive-receiving slit 3157 and the second slot 3154. The adhesive cures to form a colloid.

[0076] In the embodiments of this application, the two first adhesive-receiving seams 3156 and the two second adhesive-receiving seams 3157 share a second slot 3154. That is, the second slot 3154 is simultaneously connected to the two first adhesive-receiving seams 3156 and the two second adhesive-receiving seams 3157. The glue can flow into the two sub-slots 3153a respectively through the second slot 3154. The purpose of simplifying the structure of the groove 3152 is achieved by sharing the second slot 3154.

[0077] like Figure 7 and Figure 10 As shown, the side surface of each plug arm 6111a facing away from the partition 3155 is in contact with the groove wall of the corresponding sub-groove 3153a. The surface of each plug arm 6111a in the thickness direction is in contact with the groove wall of the corresponding sub-groove 3153a.

[0078] In this embodiment of the application, the surfaces of the two plug arms 6111a facing away from each other are limited by the groove walls of the two sub-grooves 3153a, and the surfaces of the two plug arms 6111a in the thickness direction are also limited by the groove walls of the two sub-grooves 3153a. Therefore, when the two plug arms 6111a are inserted into the two sub-grooves 3153a respectively, the groove walls of the two sub-grooves 3153a can position the auxiliary moving spring 610.

[0079] like Figure 10 As shown, the groove edge of the sub-groove 3153a is provided with a chamfer 3153b. In one embodiment, the chamfer 3153b can be a C-shaped chamfer, an R-shaped chamfer, etc., and this application does not limit it.

[0080] In the embodiments of this application, the groove edge of the sub-groove 3153a is provided with a chamfer 3153b, which is beneficial to guide the insertion action of the insertion arm 6111a and improve the insertion efficiency.

[0081] like Figure 6 As shown, the sidewall of the second slot 3154 has a bevel 3154a, which is connected to the opening of the first slot 3153 and extends obliquely away from the second insertion part 6112.

[0082] In the embodiments of this application, on the one hand, the inclined direction of the inclined surface 3154a helps the glue to flow quickly from the second slot 3154 to the first glue-containing slot 3156 and the second glue-containing slot 3157, avoiding glue overflow; on the other hand, the glue-containing space in the area where the inclined surface 3154a is located becomes larger, and after the glue solidifies to form a colloid, the space can be filled with more colloid, improving the strength and stability of the auxiliary moving spring after it is connected to the armature assembly.

[0083] like Figure 8 As shown, each contact portion 612 has multiple elastic arms 6121 and multiple auxiliary stationary contacts 6122. The multiple elastic arms 6121 of each contact portion 612 are arranged side by side along the insertion direction, and each elastic arm 6121 is provided with at least one auxiliary stationary contact 6122. The auxiliary moving contact 6122 is used to contact or separate from the auxiliary lead-out member 620.

[0084] In the embodiments of this application, an auxiliary lead-out member 620 can simultaneously contact or separate from the auxiliary moving contacts 6122 of multiple elastic arms 6121 at one end of the auxiliary moving spring 610. When one or more auxiliary moving contacts 6122 at one end of the auxiliary moving spring 610 separate from the auxiliary lead-out member 620, the remaining auxiliary moving contacts 6122 can still maintain contact with the auxiliary lead-out member 620. This improves the fault tolerance rate of the auxiliary moving spring 610 and the two auxiliary leads 620 maintaining a conductive state, thereby improving the reliability of the auxiliary moving spring 610 and the auxiliary lead-out member 620 reaching the contact separation state of the monitoring contact portion 200.

[0085] In one embodiment, each contact portion 612 has two elastic arms 6121, but is not limited thereto.

[0086] The auxiliary lead-out component 620 is fixedly disposed relative to the coil assembly 320. For example... Figure 4 As shown, the housing 100 also includes a fixing member 130, which is fixedly connected to the base 120 and covers at least a portion of the armature assembly 310, providing motion guidance for the armature assembly 310. The fixing member 130 has two through holes 131 extending through the fixing member 130 along its thickness direction. Two auxiliary leads 620 are mounted on the base 120 and pass through the two through holes 131 respectively.

[0087] In this embodiment, the auxiliary lead-out member 620 is connected to both the base 120 and the fixing member 130, meaning that there are two fixing points between the auxiliary lead-out member 620 and the outer shell 100. This improves the firmness and stability of the connection between the auxiliary lead-out member 620 and the outer shell 100, and avoids the auxiliary lead-out member 620 from being misaligned or bent due to repeated contact between the auxiliary moving spring 610 and the auxiliary lead-out member 620, thus ensuring the accuracy of monitoring.

[0088] As an example, such as Figure 4 As shown, the fixing member 130 has multiple protrusions 132 arranged circumferentially around the outer periphery of the auxiliary lead-out member 620, and the surfaces of the multiple protrusions 132 facing the auxiliary lead-out member 620 form a through hole 131, that is, the inner side of each protrusion 132 constitutes part of the hole wall of the through hole 131. The outer periphery of the auxiliary lead-out member 620 abuts against the multiple protrusions 132. When the auxiliary lead-out member 620 is inserted into the through hole 131, the protrusions 132 can abut against the auxiliary lead-out member 620, ensuring the stability of the position of the auxiliary lead-out member 620. In addition, the protrusion 132 can reduce the contact area between the hole wall of the perforation 131 and the auxiliary lead-out member 620, thereby reducing the amount of scraping generated by the mutual friction between the auxiliary lead-out member 620 and the fixing member 130 during the assembly process, and reducing the hole wall area of ​​the perforation 131, making the hole wall of the perforation 131 less prone to deformation during the forming process, and making the hole wall position easier to control, thereby making it easier to control the positioning accuracy of the perforation 131 on the auxiliary lead-out member 620.

[0089] In one embodiment, the auxiliary lead-out 620 can be inserted into the opening 122 of the base 120, and the auxiliary lead-out 620 is fixedly connected to the base 120 by a dispensing process. In another embodiment, the auxiliary lead-out 620 can also be interference-fitted with the wall of the through hole 131.

[0090] like Figure 1 As shown, a portion of the auxiliary lead-out member 620 extends from the surface of the top cover 110 facing away from the base 120.

[0091] Of course, in other embodiments, a portion of the auxiliary lead-out member 620 may extend from the side surface of the base 120 facing away from the top cover 110, instead of extending from the outer surface of the top cover 110.

[0092] like Figure 9 As shown, the contact portion 200 includes two contact components, and the armature assembly 310 is used to drive the two contact components to switch between a closed state and an open state.

[0093] Understandably, the armature assembly 310 can be directly connected to the two contact assemblies, or it can be connected to the two contact assemblies via a push rod.

[0094] Each contact assembly includes a moving spring, a stationary contact, a moving contact, and a lead-out terminal. The moving spring has a fixed end and a movable end. The stationary contact is mounted on the fixed end and is connected to the lead-out terminal. The moving contact is mounted on the movable end.

[0095] For ease of explanation, the two contact components are defined as the first contact component 210 and the second contact component 220, respectively. The first contact component 210 includes a moving spring, a stationary contact, a moving contact, and a lead-out terminal, defined as a first moving spring 211, a first stationary contact 212, a first moving contact 213, and a first lead-out terminal 214. The first moving spring 211 has a first fixed end 2111 and a first movable end 2112. The first stationary contact 212 is mounted on the first fixed end 2111, and the first stationary contact 212, the first fixed end 2111, and the first lead-out terminal 214 are fixedly connected. The first moving contact 213 is mounted on the first movable end 2112. The second contact assembly 220 includes a moving spring, a stationary contact, a moving contact, and a lead-out terminal, defined as a second moving spring 221, a second stationary contact 223, a second moving contact 222, and a second lead-out terminal 224. The second moving spring 221 has a second fixed end 2211 and a second movable end 2212. The second stationary contact 223 is mounted on the second fixed end 2211, and the second stationary contact 223, the second fixed end 2211, and the second lead-out terminal 224 are fixedly connected. The second moving contact 222 is mounted on the second movable end 2212.

[0096] It is worth noting that, in this embodiment, the fixed end and the movable end refer specifically to the two ends of the movable spring along its length direction, rather than the two end faces of the non-movable spring along its length direction.

[0097] In one embodiment, the first fixed end 2111, the first movable end 2112, the second fixed end 2211, and the second movable end 2212 are all sheet-like structures, but are not limited thereto.

[0098] In this design, the movable ends of the two contact components are respectively located on the same side of the fixed ends corresponding to the movable ends in the two contact components. That is, the position of the first movable end 2112 of the first movable spring 211 corresponds to the position of the second fixed end 2211 of the second movable spring 221, and the position of the second movable end 2212 of the second movable spring 221 corresponds to the position of the first fixed end 2111 of the first movable spring 211. Furthermore, the first movable end 2112 and the second movable end 2212 are located on the same side of the first fixed end 2111 and the second fixed end 2211, respectively.

[0099] The magnetic circuit drive portion 300 is located on the side of the two movable ends facing away from the two fixed ends. In the embodiment of this application, the magnetic circuit drive portion 300 is located on the side of the first movable end 2112 facing away from the second fixed end 2211, and the magnetic circuit drive portion 300 is located on the side of the second movable end 2212 facing away from the first fixed end 2111.

[0100] The magnetic circuit drive part 300 is positioned on the side of the movable end facing away from the fixed end, so that the magnetic circuit drive part 300 can be far away from the fixed end and the lead-out terminal. This reduces the influence of the magnetic field generated after the fixed end and the lead-out terminal are energized on the magnetic circuit drive part 300, improves the reliability of the magnetic circuit drive part 300, and at the same time makes the drive of the magnetic circuit drive part 300 on the first movable end 2112 and the second movable end 2212 free from interference from the first fixed end 2111 and the second fixed end 2211.

[0101] Of course, in other embodiments, the first movable end 2112 may also be located on the side of the second fixed end 2211 facing away from the magnetic circuit drive portion 300, and the second movable end 2212 may be located on the side of the first fixed end 2111 facing away from the magnetic circuit drive portion 300.

[0102] The armature assembly 310 of the magnetic circuit drive section 300 is connected to both the first movable end 2112 and the second movable end 2212, and is used to simultaneously drive the first movable end 2112 to move relative to the second fixed end 2211 and the second movable end 2212 to move relative to the first fixed end 2111, so that the first movable end 2112 drives the first moving contact 213 to contact or separate from the second stationary contact 223 and the second movable end 2212 drives the second moving contact 222 to contact or separate from the first stationary contact 212.

[0103] It is understandable that the armature assembly 310 can be fixedly connected to the two movable ends or movably connected. When the armature assembly 310 is movably connected to the two movable ends, the armature assembly 310 can be connected to the two movable ends respectively through two elastic elements.

[0104] It is understood that the armature assembly 310 can be directly connected to the first movable end 2112 and the second movable end 2212, or it can be connected to the first movable end 2112 and the second movable end 2212 via a push rod.

[0105] When the contact portion 200 switches from the open state to the closed state, the armature assembly 310 drives the first movable end 2112 and the second movable end 2212 to move closer to the second fixed end 2211 and the first fixed end 2111, respectively, so that the first moving contact 213 contacts the second stationary contact 223 and the second moving contact 222 contacts the first stationary contact 212.

[0106] When the contact portion 200 switches from the closed state to the open state, the armature assembly 310 drives the first movable end 2112 and the second movable end 2212 to move away from the second fixed end 2211 and the first fixed end 2111, respectively, so that the first moving contact 213 separates from the second stationary contact 223 and the second moving contact 222 separates from the first stationary contact 212.

[0107] Therefore, in the relay of this application embodiment, the movable ends of the two contact components are respectively disposed on the same side of the fixed ends corresponding to the movable ends of the two contact components. The movable ends of the two contact components are driven by the same magnetic circuit driving part 300 to realize the switching of the two contact components from closed state to open state and from open state to closed state. Thus, the movement space required by the movable ends of the two contact components when closing or separating is located on the same side of the fixed ends of the two contact components. In this way, only one side of the fixed ends of the two contact components needs to be reserved, instead of reserving space on both sides of the fixed ends of the two contact components. This allows the structure of the two contact components and the magnetic circuit driving part 300 to be designed more compactly in the driving direction, thereby significantly reducing the size of the internal space occupied by the two contact components in the relay, which is beneficial to the miniaturization design of the product.

[0108] like Figure 9 As shown, the lead-out terminals are sheet-like structures, and the lead-out terminals of the two contact components are arranged on the same plane, that is, the first lead-out terminal 214 and the second lead-out terminal 224 are arranged on the same plane.

[0109] like Figure 9 As shown, the first moving spring 211 and the second moving spring 221 are arranged in a cross configuration.

[0110] In one embodiment, the intersection area of ​​the first moving spring 211 and the second moving spring 221 is located between two corresponding sets of moving contacts and stationary contacts. Specifically, the first moving contact 213 and the second stationary contact 223 are defined as the first set of contacts, the second moving contact 222 and the first stationary contact 212 are defined as the second set of contacts, and the intersection area of ​​the first moving spring 211 and the second moving spring 221 is located between the first set of contacts and the second set of contacts.

[0111] In the embodiments of this application, the intersection area of ​​the first moving spring 211 and the second moving spring 221 is located between the two sets of contact groups, making full use of the space between the two sets of contact groups without occupying other areas, further reducing the space occupied by the two contact components, which is conducive to the miniaturization design of the product.

[0112] In one embodiment, the first fixed end 2111, the first movable end 2112, the second fixed end 2211, and the second movable end 2212 are all flat plates. When the contact portion is in a closed state or the first movable spring 211 and the second movable spring 221 are in a natural, undeformed state, the plane where the first fixed end 2111 of the first movable spring 211 is located is parallel to the plane where the first movable end 2112 is located, and the plane where the second fixed end 2211 of the second movable spring 221 is located is parallel to the plane where the second movable end 2212 is located.

[0113] In the embodiments of this application, the plane where the fixed end of the movable spring is located is parallel to the plane where the movable end is located, making the structure formed by the cross arrangement of the first movable spring 211 and the second movable spring 221 more compact and further reducing the space occupied inside the relay.

[0114] Of course, in other embodiments, the first moving spring 211 and the second moving spring 221 may also be configured as straight-plate structures with the portion between the moving contact and the stationary contact, and the first moving spring 211 and the second moving spring 221 are arranged in an "X" shape after being crossed.

[0115] In one embodiment, the coil assembly 320 is configured to drive the armature assembly 310 to move linearly in response to an input signal, thereby moving the first movable end 2112 and the second movable end 2212, and the auxiliary moving spring 610 is located on one side of the armature assembly 310 in the linear movement direction.

[0116] In one embodiment, the moving direction of the armature assembly 310 is parallel to the thickness direction of the first fixed end 2111.

[0117] Compared to the rotating design of the armature drive part in the prior art, the armature assembly 310 of this application embodiment is designed to move in a straight line, which does not have the problem of radial component loss, and has the advantages of simple structure, simplified assembly process and not occupying too much space.

[0118] In summary, the relays of the embodiments of this application have at least the following advantages and beneficial effects: In the relay of this application embodiment, the auxiliary moving spring 610 and the armature assembly 310 are connected by a plug-in method. On the one hand, the auxiliary moving spring 610 and the armature assembly 310 can be molded separately, which reduces the processing difficulty of each component; on the other hand, the plug-in connection method can improve the assembly efficiency of the auxiliary moving spring 610 and the armature assembly 310.

[0119] Furthermore, the auxiliary lead-out component 620 is connected to both the base 120 and the fixing component 130, meaning that there are two fixing points between the auxiliary lead-out component 620 and the outer shell 100. This improves the firmness and stability of the connection between the auxiliary lead-out component 620 and the outer shell 100, and avoids the auxiliary lead-out component 620 from being misaligned or bent due to repeated contact between the auxiliary moving spring 610 and the auxiliary lead-out component 620, thus ensuring the accuracy of monitoring.
